' Application filed September 4, 1924. Serial No. 735,807. 4

To all whom it may concern:

Be it known that I, BEN KING FORD, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Apparatus for Whipping (jores with Strand Material, of which the following is a full, clear, concise, and exact description.

This invention relates to an apparatus for whipping cores with strand material, and more particularly to an apparatus for whlpping the ends of telephone cords preparatory to securing terminals thereto. I

The object of the invention is to provide an improved apparatus for whipping cores with strand material.

In accordance with the general features of the invention there is provided a whipping finger, which receives the wire from a supply source and whips it about the end of a cord carried upon a ,stat1onary support. Carried by the whipping finger is a reciprocable member which is adapted to distribute the wire in a spiral formation along the cord while the support and the whipping finger remain in relatively fixed positions along the axis of the cord.

The accompanying drawings disclose an improved apparatus for whipping the cord, the major portion of which apparatus is more fully disclosed in Patent 1,497,679, June 17, 1924, issued to H. H. C. Grondahl.

It will be noted that in the structure disclosed in the above mentioned patent, the cord support is moved back during the whipping operation so as to cause the w1re to be whipped about the cord in spiral formation, whereas means carried by the whipping finger is disclosed herein for causing the wire to be whipped around the cord in spiral formation, .and the cord support is maintained in a stationary position at all times.

Other objects and features of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings which illustrate one embodiment thereof, and in which Fig. 1 is a fragmentary side elevation of the complete mechanism with a section of the cover removed;

Fig. 2 is an enlarged view of the whipping finger as shown in Fig. 1;

Fig. 3 is a plan view of the finger shown in Fig. 2;

Fig. 4 is a section taken on the line 4-4: of Fig. 2 looking in the direction indicated by the arrows;

Fig. 5 is a fragmentary central sectional view of a portlon of one end of the main driving shaft;

Fig. 6 is a view of the cord after it has been removed from the whipping meeha msm, and

Fig. 7 is a diagrammatic View showing the way a wire is laid on the end of the cord.

Referring now to the drawings in detail in which like reference numerals designate similar parts throughout the several views, 114 denotes a wire which is threaded from a supply spool 115, through a hollow shaft 16, through a slot 199 in a rectangular rod 201, of rectangular cross-section, through a passage 131 and around a guide roller 128 of a whipping finger 126, and through a hole 200 in the end of the'reciprocatory rod 201 (Figs. 2 and 3). A conductor or cord support 87 is provided with a V-shaped depresslon 135 within which the end of the cord to be whipped is placed with its end projecting a suitable distance into a U- shaped formation of the whipping finger The rod 201 passes through a passage 202 in the whipping finger 126, and a passage 203 in the hollow shaft 16 (Fig. 4). Formed in the shaft 16 (Fig. 5) is a slot 201 in which rides a pin 205 secured at one end to the rod 201 and attached at the other end to a collar 206.

Extending from a bearing 14 and secured thereto is a supporting member 207 in which is reciprocably mounted a bar 208 (Fig. 1) which is mounted suificiently far enough away from the whipping mechanism so as not to interfere therewith and is parallel to both the machine and a bench 10. A shaft 62 has been made longer than the one disclosed in the above noted patent and extends outwardly through a slot 209 in the bar 208, the slot 209 permitting the bar 208 to be reciprocated. Mounted on and splined to the shaft 62 on the outer side of the bar 208 is a cam 80 which is adapted to engage a cam roller 210 rotatably attached to one end of the bar 208. Pivotally' secured to the other end of the bar 208 is a lever 211 pivoted at a point 212 to a frame 13. An

end 213 of'the lever 211 is forked and is adapted to straddle the collar 206 in such a manner as to permit the collar 206 to revolve with the shaft 16. Secured to one end of the bar 208 is a spring 214, the other end of which is secured at a point 215 to the frame 13.

It will be noted that the support 87 as disclosed herein is rigidl secured to the frame 13, and thatv the mec ianism associated with the cam 80 disclosed in the above noted patent for moving back the cord support has been removed.

The whipping strand 114 is withdrawn through the hole 200 in the end of the rod 201 and looped around a pin 134 in the support 87 and then over a knife edge 129 in the whipping finger 126. -A cord to be whipped is then placed on top of the, looped end of the strand in the V-shaped depression 135 with its end projecting a suitable distance into the U-shapedformation of the whipping finger 126. Upon the depression of a lever 28, the whipping mechanism is set in operation causing the cam80 to revolve as is described morein detail in the above noted patent. The cam 80 in revolving moves the roller 210 and the bar 208 longitudinally of the whipping mechanism. The bar 208 in moving in the direction indicated by the arrow causes the lever 211 to pivot upon the point 212, drawing the rod 201 inwardly away from the end of the cor-cl and distributing the wire in spiral formation along the core as the wire is whipped on the cord by the revolving whipping finger 126.

When the whipping operation has been completed, the cam 80as described in the above noted application, is caused to be forced back into its original position and the roller 210 and the bar 208 are drawn back to their normal positions by the spring 214. The bar 208 in returning to its normal position through the lever 211 causes the rod 201 to be returned to its original position. v

The cord is then removed from the support 87 and the wire 114 severed therefrom, the finished cord being clearly shown in Fig. 6. It is believed that the manner in which the wire is laid on the cord will be readily apparent from the diagrammatic view shown in Fig. 7.

WVhat is claimed is:

1. In a mechanism for whipping acore with a strand, a whipping finger provided with means for causing the strand to be whipped spirally. around the-core.

2. In a mechanism for whipping a core with a strand, a whipping finger provided with means for causing the strand to be distributed in spiral formation around the core.

3. In a mechanism for whipping a core with a strand, a finger for whipping the strand around the core, and means carried by the whipping finger for causing a rela tive movement between the whipping finger and the strand to cause the strand to be whipped around the core.

4. In a mechanism for whipping a core with a strand, a finger for whipping the strand around the core, and a reciprocable element carried by the whipping finger for causing the strand to be wound around the core in spiral formation.

5. In a mechanism for whipping a core with a strand, a finger for whipping the strand around the core, means carried by the said whipping finger for causing the strand to be whipped around the core in spiral formation, and means for forming a loop in the end of the strand.

6. In a mechanism for whipping a core with a strand, means for whipping the strand around the core, means carried by the whipping means for causing the strand to be whipped around the core in spiral formation, a support for the core, and means associated with the said support for forming a loop in the end of the strand. I

7. In a mechanism for whipping a core with a strand, means including a rotatable element for whipping the strand around the core, and a member carried by the rotatable element adapted to be moved longitudinally of the core.

8. In a mechanism for whipping a core with a strand, means including a rotatable finger for whipping the strand around the core, and a reciprocatory member carried by the rotatable finger for causing the strand tobe whipped around the core in spiral formation.

9. In a mechanism for whipping a core with a strand, a finger for whipping a strand around the core, and means within the finger for distributing the strand around the core in spiral formation.

In witness whereof, I hereunto subscribe my name this 25th day of August A. D., 1924.

BEN KING FORD.
